My favorite talk yesterday was done by Werner Pieper, which was mainly a collection of anecdotes about him being a former drug-dealer. He presented some interesting thoughts and experiences about trust in the illegal world. He also had some interesting stories about piracy-prints.
Today, I watched a talk about TPM and MacOS, which led to a very angry reply at the end by Rüdiger Weiss (who did a lot of work and interesting talks about trusted computing in the past years), sadly there wasn't any time left. Also about DRM, later this day there was a sadly very rarely visited talk by Seth Schoen from the EFF about television standards and the DRM-discussion in the DVB-group (DVB is the european digital video standard). Very detailed information, also many things I didn't know, for example that the industry plans to implement devices that only work in certain areas (by GPS-modules) or in a specific household. Most people seemed to have attended the talk by their »popstar« (Lawrence Lessig), who was placed in the same time slot.
Beside that, I sat some time at the CAcert-booth, helping them assuring visitors. Had some nice talks there and had the feeling that CAcert is really getting forward these days. For example I didn't know till now that Indymedia is using CAcert for their open posting.
Beside that, some people asked me about my desktop-background, it's from an anti-drm/itunes-campagne by the free software foundation and you can find it here.
